1. A method for determining reference signals, the method comprising:

  • obtaining, by a User Equipment (UE), at least one of group hopping information and sequence hopping information of a UE-specific reference signal from cell-specific system information broadcasted by an enhanced Node B (eNB);

    receiving, by the UE, UE-specific control information transmitted by the eNB to the UE;

    generating, by the UE, a UE-specific reference signal of a first slot according to at least one of the group hopping information and the sequence hopping information of the broadcasted UE-specific reference signal; and

    if the UE-specific control information indicates that at least one of group hopping and sequence hopping of UE-specific reference signals is disabled, generating a UE-specific reference signal of a second slot in a same frame with the first slot according to the UE-specific reference signal of the first slot.
